Watch Out For These Hidden Fees

Booking.com adds a 14.5% "taxes and fees" charge at checkout not shown in the headline price—this made my $105 Spirit booking cost $121. Delta's $45 bag fee applies to all checked luggage, even on "free" economy tickets. I learned this when my $92 Delta flight from Atlanta in March 2025 included a $45 bag fee that wasn't visible until payment. Always check the final total before confirming.
